The free plan needs no card. The API tools pass paths and JSON bodies through without validation, every key is limited to 60 requests a minute, and audit logs are Enterprise only.\n\n**Woopra.** Woopra's REST API returns saved Trends, Journeys, Retention and Attribution reports, profiles and raw session logs, with published limits of 300 calls a minute and 3,000 a day per project. A report must first be built in the web app, the tracking endpoints accept events without a secret by default, and no changelog or SLA was found.\n\n## Before you call either\n\n### GrowthBook\n\n1. Connect to https://mcp.growthbook.io/mcp and complete OAuth in a browser. Use https://mcp.growthbook.io/mcp/api for the two API tools alone\n2. Call `growthbook_list_skills` and `growthbook_read_skill` before writing. The API tools don't validate payloads, so use the paths the skill names\n3. Stay under 60 requests a minute per key. On 429 wait for the `RateLimit-Reset` seconds before retrying\n4. List calls return 10 items by default. Pass `limit` up to 100 and `offset` to page\n5. A 422 is a soft warning. Resubmit with `?ignoreWarnings=true` only after reading the message\n\n### Woopra\n\n1. Ask the owner to build and save each report in the web app first, then pass the last path segment of its URL as `report_id`\n2. Authenticate REST calls with HTTP Basic, using the App ID and Secret Key from the Access Keys tab, against `https://www.woopra.com/rest/3.10/`\n3. Stay under 300 calls a minute, 600 an hour and 3,000 a day per project. A 429 carries no documented retry interval, so back off on your own schedule\n4. Reuse the `snapshot` ID from the first response when paging with `offset`, or pages past 1,000 records may not agree\n5. Send `cookie` or a `cv_` identifier such as `cv_email` on every track call. Without one the event lands on a random profile that can't be identified later\n6. When reading `/logs/export`, delete the profile named in each `type: \"delete\"` line. The following lines log its data again under `new_id`\n\n## Questions\n\n### Which is better for AI agents, GrowthBook or Woopra?\n\nGrowthBook scores 70.1 (BB) on agent readiness against Woopra's 44.4 (E), and leads in every scored category.\n\n### Do GrowthBook and Woopra need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call GrowthBook and Woopra without installing anything?\n\nYes. GrowthBook has a hosted endpoint at https://mcp.growthbook.io/mcp and Woopra at https://www.woopra.com/rest/3.10.\n\n### Are GrowthBook and Woopra open source?\n\nGrowthBook is open source (MIT for the core and for the MCP server. Three enterprise directories in the main repository are under GrowthBook's enterprise licence. GrowthBook Cloud is a hosted service under the Customer Agreement). No open-source release is listed for Woopra.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/growthbook-vs-woopra.json, and with the fewest tokens: https://www.anchorterminal.com/compare/growthbook-vs-woopra.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"growthbook\", \"b\": \"woopra\"}`.
